RMS Current Calculator

Formula

The formula to calculate the RMS current is:

\[ I_{rms} = \frac{P_{ave}}{V_{rms}} \]

Where:

\( I_{rms} \) is the RMS Current (amps)
\( P_{ave} \) is the Average Power (watts)
\( V_{rms} \) is the RMS Voltage (volts)

What is RMS Current?

RMS current is the root mean square value of the current, which is a measure of the effective value of the varying current. It is commonly used in AC circuits to represent the equivalent DC value that would produce the same power dissipation.

Example Calculation

Let's assume the following values:

Average Power (Pave): 100 watts
RMS Voltage (Vrms): 50 volts

Using the formula to calculate the RMS current:

\[ I_{rms} = \frac{100}{50} = 2 \text{ amps} \]

The RMS current is 2 amps.
